The spooling machine is mounted on a bed-plate 1 to which are rigidlysecured brackets 2, 3, 4 and 5 which carry or'support the spindles,rods, levers and the like hereinafter described.

The plate 1 further carries several small bearings for the spoolconveying apparatus. Between the brackets 2 and 3 is rotatably mountedin bearings, a Worm 6, on an extension of which to the right is mounteda loose pulley 7, as well as a fast pulley 8, (Fig. 12). The Worm 6 ishollow and within it is disposed a hollow spindle 9 and made in twosections and provided with coupling teeth Figs. 11 and 12. At the lefthand end. the spindle 9 is provided with a pair of collars forming agroove 11 with which the fork 56 engages for a purpose hereinafter morefully described.

To the spindle 10 is rigidly secured a pulley 63. The right hand end ofthe spindle 10 is slotted and also provided with a bolt hole 12 To thesame ortion-of the spindle 10 is rlgidly secured a ead 13 which isrovided with a slot receiving the thread ho der 15 rotatable about a in14, a groove 16 is also provided on the ead 13. The head 13 is turned atits front face to form a spool holder. Within the spindle 9, 10 isarranged a spindle 17 provided at its left hand end with collars forminga groove 18, and on the righthand end adjustably connected, by means ofa pin 19, to the thread holder 15 secured to the head 13 and formed as abell crank lever. To the bracket 4 is secured on a bolt 21 Figs. 1, 2,13 and 14, a fiat spiral spring 20 provided with a projection 22 shapedto. engage intermittently with the groove 16 of the head 13 and stop itsrotation in such manner that the thread holder 15 takes up a definiteposition.

The worm 6 driven by a main driving belt 23 which passes over the pulley8, drives in its turn a worm wheel 24 rigidly secured to a spindle 27mounted in bearings 25 and 26. To the spindle 27 are further securedeccentrio disks orcams 28, 29, 30 and 31, as well as a bevel wheel 32.The cam disk 28 is, in its turn, connected to the rod 33 carrying at theleft hand end a roller 34. The rod 33 is provided with a groove 35 and aspline or key 36, and the belt shifter 37 is secured to it. Springs 38and 39 are used for moving the rod 33. A lever 41 42 rotatable about apin 40 is moved simultaneously with the rod 33 and engaging by means ofits bifurcated end 41 therewith while another arm 42 forms a support forthe spool holder 43 mounted in the bracket 5, and a third arm 44 is alsobifurcated and engages with a groove provided at the rear end of thespool holder 43. To the rod 33 is also secured a collar 45 which engagesthe lever 41. The key or spline 36 is adapted to move as shown in Fig.1, in front of the spring 20 or away from the same.

The cam disk 29, is adapted to strike a connecting rod 47 provided witha roller 46 and connecting the lever 49 pivoted about a pin 48 (Figs.4-6) to the thread cutting apparatus. The spring 50 presses the connecting rod 47 in any position firmly against the cam 29. The cam 30engages a branch 52 of a bell-crank lever 52, 53, pivoted about a pin51, the other arm 53 being provided with which engages the cam 67, movesthe spool a pin 54, adapted to engage a fork 56 secured to a helicalspring 55 and engaging, in its turn, with the annular groove 11 of thespindle 9 and adapted to uncouple it from or to couple it to the spindle10. The cam 31 drives a bell-crank lever 58,-59 pivoted about a pin 57,the arm 58 of which lever is engaged by the cam 31, while the arm 59presses with its pin 60 against a fork 62 se cured to a helical spring61 and engaging in its turn with the annular groove 18 of the spindle 17to press the thread holder 15 against the spool or to lift it ofi'fromthe same.

The bevel wheel 32 engages with a corresponding toothed wheel 64 securedto the head of the spindle 65 supported in the brackets 3 and 4. On thespindle 65 are further mounted cam disks 66 and 67, as well as a chainwheel 68, I

Owing to the movement of the two cams 66 and 67 (Fig. 8) in coiiperationwith rods and the like, the spool feeding apparatus 69 is raised andlowered by the cam 66, while the cam 67 imparts to it an oscillatingmovement for bringing in the empty spools.

Under the cam disk 66 slides the lever 70 rigidly secured to the spindle71 and adapted to raise and lower the spool feeder. The spindle 17 issupported in the two brackets 72 and '73, and to it are rigidlyconnected levers 74 and 75 carrying the spindle 76 of the spool feeder69 (Figs. 4 and 5). p

The connecting rod 33 when moved into its right halrd end positionallows the lever 78, 79 (Fig. 3) to engage with its portion 78, thegroove 35.

The spring 38 issecured to a bolt or pin fixed on the bed plate 1 andpushes the rod 33 toward the left onto the eccentric 28 when thearm 78of the lever 78, 79 is disengaged from the groove 35 of the rod 33 afterthe spool is fully wound. The spring 39 is secured to the rod33, that isto say between the spring 38 and the fork shaped lever 41.- The doublelever 41, 42 is loaded -more or less by the spring 38,- in accordancewith the position of the rod 33, in order to limit the movement of thespool holder 43.

The spring 80 (Fig. 8) and-the lever 81 prevent a jerky movement as thelever 77 feed device forward. A lever 49 is slidably connected to therod 47, the said lever being connected to the segment 86 which isattached to the l shears 84, 85,.by a lever 87.

The rod :47 has a pin 105 thereon and the fork 83 is locked by a device88 releasedby the said pin, a spring 89 then moving the fork 83. Aspring 91 acts on the locking book 88. The fork is returned by the pin90.

' The conveyer device for the empty spools consists of a casing 92 witha front structure 93 through the opening 94 of which,

which can be closed, the empty spools are introduced In the interior ofthe casing 92, to the spindle 94 is secured a wheel 95 with blades 96adjustable in the radial direction of the wheel. The direction ofrotation of the wheel 95 is shown by the arrow in the drawing and iseffected by the chain wheel 97 mounted on the spindle 94, connected bythe chain 98 to the chain wheel 99, the ratio between the two wheels inquestion being calculated in accordance with the working of themechanism, the conveyer device being arranged in front of an opening.100. I

The posit-ion of the opening 100 on the casing 92 is such that duringthe rotation of the wheel 95, the blades 96 of which always assume sucha position that, owing to their shape only one spool can fall from theopening 100 into the catching and conveying device, for the reason thatthe rear portion of eachblade 96, when in front of the open ing 100,forms an oblique plane and causes the other spools resting on the same,to roll backward to the center (Fig. 8).

The catching 'and conveying device con-,

sists of several spindles, chain wheels and corresponding chains. On thespindle 103 mounted in bearings 101 and 102, are mounted the chainwheels 99 for the movement of the wheel 95', and 104 for the con-.

veyer device connected by a chain 106 to the chain wheel 107. The chainwheel 107 is mounted on the spindle. 110 supported in bearings 108 and109 and carrying more-' over the chain'wheel '111 which in its turn isconnected by means of the chain 112 to the chain wheel 68. is mountedonfthe spindle 65. On the said chain 106; are mounted the collecting andconveying hooks 113 which eject the spool 82 taken up,,into the spoolfeeder 69. r

The thickness of winding 'of the spools is regulated by a'devicearranged on two supports 114 of the spool feeder 69 at the frontportion. The bottomportion 115 is rota- The chain wheel 68' tablyconnected, by means of a bolt 116. to the spool feeder 69 and slideswith its free end: over the bed-plate 1 (Figs. 1-3 and 8).'

On the partv is rotatably mountedabout a pin 117 the lever 78, 79, thearm 79 of which is provided with a spring 118 which can be shifted bymeans of a screw 119. The lower lever arm 78 fits intothe groove 35 ofthe connectingrod33. Over the bottom portion 115 ,which comprises a pairof ribs is arranged a sliding trahk 120 onwhich the wound spools rollinto the receiver. The lever 78, 79,. is arranged between the two ribs115, which act as runners, bearing on the rod 33 during the slidingmotion of the part 120, 115.

The arrangement of the above-described mechanism will be clearly seenfrom Fig. 3.

The operation of the automatic 'spooling pulley machine is as follows:The machine is driven by the main belt 23 leading from the of thesource of power through the table and the bed-plate 1 to the' machine.The empty spools are thrown into the drumlike receiver 92, the width ofwhich is made to suit the length of the spools, and guided by the Wheel95 rotatably mounted therein.

Owing to the construction of the single buckets, only one spool at atime is brought in front of the opening 100 of the receiver whence itfalls into the box provided with the catching and comeying device 106 byvmeans of which the said spool is supplied to the spool feeder 69; Thespool feeder 69 brings the spool into the spool holder 43.

After the spool feeder, owing to a corresponding movement of the cam 67and the lever 77 on the spindle 76 has made an oscillation to the right(Fig. 8) for receiving an empty spool and thereupon returned to its orignal position, the driving belt 23 is pushed over by the cam 28, rod 33and belt shifter 37, to the fast pulley 63. In the meantime, theconnecting rod 33 has j been pushed by the cam 28 to the right into theend posit-ion, inwhich a lever 78, 79 engages with its lower arm 78 withthe groove 35, the key or spline 36 mounted on' the rod 33, beingsimultaneously withdrawn from the spring 20 resting on it, theprojection 22 of which spring engages then with the groove 16 and stopsthe head 13 in such manner that the thread holder 15 is above the spool.When the spool feeder moves forward, the cam disk 28 releases the rod33, which enables the spool holder 43 to move back, so that thecompletely wound spool can be ejected, and a new empty spool 82 fixed.The cam disk 29 and sprin 50 move the connecting rod 47 forward andbackward, and in that way, after the insertion of the empty spool 82,the fork 83 brings the thread under the thread holder 15 between thebranches or blades 84 and 85 Figs. 4 and 5 of the shears, and the threadis cut off at the next moment. The fork 83 is provided with threefingers, a, 7), 0. (see Fig. 7 from left to right) which effect incommon the conveying of the thread between the shears blades 84, 85 andunder the thread holder 15, in such a manner that the said thread cannottake any other course. The fingers a and b have for their purpose tobring the thread between the blades 8t, 85 whereas the fingers b and 0are intended to bring the thread under the thread holder 15. Thisoperation takes place immediately after the wound spool has beendischarged and after the empty spool has been set in place by the spoolfeeder 69. As soon as a spool 82 has been wound to a sufficient extent,it disengages the locking lever 7 8 79 from the notch 35 of the rod 33,whereby the latter is pushed to the left.

The movable spring 118 comes into contact with the "wound spool 82, thespring 118 being fixed to the lever arm 79 and its movement istransmitted to the lever 78, 79 or disengages the lever arm 78 from thegroove 35 of the rod 33 when the spool 82 is fully wound, this beingregulated by the set screw 1 19 according to the winding thickness to beobtained. In that way, first of all the belt 23 is shifted to the pulley8 driving the exchange device, and consequently the spool holders 13 and43 are released. In that way, the spool feeder 69 is brought with anempty spool between the spool holders, and ejects the wound spool. Theejected wound spool remains until the connecting thread is cut-off infront of the spool feeder, on the oblique discharge groove 120. Thewound spool then rolls down the track 120 into the receiver. The spoolfeeder 69 is lowered and moved back empty. A new empty spool is placedinto it by the conveyer chain 106. The cam 28 then moves the rod 33 tothe right, to such an extent that the locking lever 78 79 springs intoits roove 35 and holds it fast. In that way, t e belt 23 is pushed ontothe pulley G3, and the thread is wound on the empty spool. The threadholder 15 holds fast the thread until the latter is able to keepautomatically on the spool.- As soon as the belt 23 has been broughtcompletely on the pulley 63, the exchange device is again in itsposition of rest. The exchanging is effected during one revolution of.the worm wheel 24. The lever 49 adapted to be moved by the rod 47rotates in its movement a disk segment 86 connected by means of a lever87 to the rotatable blade 85 of shears 84 and 85. 'VVhen the rod 47 ismoved to the right, the shears will be opened. A pin 105 is provided onthe rod 47 for releasing a spring locking device 88 of the fork 83 whichwill then be oscillatedto the left by a spring 89 and bring thethreadunder the thread holder 15, or between the blades of the shears 84 85.During the return of the rod 47, the parts 84 of the shears are firstclosed, and the thread is cut. The fork 83 is thereupon forced back by apin 90, until owing to the action of the spring 91, it engages with thelocking hook .88. The shears 8 85 will not however cut the thread, untilthe stopped thread holder 15 is holding the thread fast on the new emptyspool. .When the belt 23 is resting on one-half of the pulley 8,.it nolonger has the power to keep the whole device working, and the bellcrank lever 52, 53 is released by the cam 30, and the spindle 9 (mountedin the worm (i and coupled to the latter by a groove and spline in suchmanner that it must participate in the rotation, but is adjustable inthe longitudinal direction to such an extent that the coupling teeth canbe brought out of &

engagement), will be coupled by the spring 61 and the fork 62 to thespindle 10. The coupling teeth remain in engagement uhtil the drivingbelt 23 has passed from the pulley 8 to the pulley 63.

For stopping the-whole machine, the loose pulley 7 is used.

For guiding the thread onto the spool any known traverse device can beused. For the sake of simplicity and cheapness it is preferable that thetraverse mechanism for a certain number of spool apparatus should beactuated in common by the main driving shaft.

- The thread for supplying the spool is obtained from theiwell-knownwound spools or the like, as delivered from the spinning mills.
